I probably did - but here's the long/short of it...

Step 1 - Replace stock factory component speakers (non-Bose) with a/d/s 345is component speakers. They fit in the stock locations. I ran new speaker wire (for each speaker) to the trunk.

Step 2 - Wire the "line out" of the Symphony radio (using the Blaupunkt adapter to get the "line out") to the trunk. This also provides a remote turn-on wire...

Step 3 - Run power from the Battery using a 4-gauge wire (and fuse) - to the trunk.

Step 4 - Mount "pretty" crossovers on the back of the rear seat, and wire to speakers.

Step 5 - Mount Alpine MVF-357 amp on side of trunk. Connect wires...(It's a 5 channel amp, 4x50, 1x150, I think)

Step 6 - Drop in an MTX 10" sub in a small box (w/velcro on botton)

All 4 doors? Or just the front? Do you recall the size of that model?

I think it is 5.25" 2-way component system, 2-3/8" DEPTH, 15 TO 100W Model 345is. Since I already have the amp wiring, and sub installed, should be not that bad for the install

5 1/4 is correct. They fit without serious mods...
